Please give us some feature to MARK FAVORITE STAPLE cards!

Give us an option to mark cards as idk '' favorite'' or something, so we don't need to search the WHOLE library again and again ...... for me it's just a down that I need to search any card again and again to find the card I wanted to have in x,y,z Deck. Yea ofc we can sort by basic, basic v, radiant blabla but I want a feature like in ptcgo where I just marked the cards I used in any deck as '' for wanted'' for example. I rly love pokemon tcg live but if I need to search the whole library again and again this is just ... a downside, a huge downside to me.
